Abstract
Of concern in this paper is a theoretical investigation of Electromagnetohydrodynamic (EMHD) flow transport of a non-Newtonian power-law fluid through a porous microchannel based on the Brinkman-Forchheimer extended Darcy model. The impact of joule heating and different viscous dissipations (the Al-Hadharami term, Darcy term and Forchheimer term) on thermal transport was analysed by considering the EMHD flow through the porous microchannel. The governing nonlinear equations are solved numerically to analyse the characteristics of velocity and temperature distributions. Observing a Nusselt number variation for different parameter values is interesting. It also indicated from the effects that the heat transfer rate performed better for the pseudoplastic fluid than the dilatant fluid. It was also significantly influenced by different viscous dissipation terms. The apprehensible changes in the temperature profiles are found due to the additional viscous dissipation terms and joule heating shown in the channel’s middle layers for all the fluids.
